class_docstr: The containing dialog and controller for the embedding
  and the image viewer that together make up an analysis
  (i.e. a user selection at an hSNE scale). It also
  iterates over the embedding once the analysis is created
  and this is dynamically displayed in the embedding gui.
docstr: The string id associated with this analysis
docstr_tok: ["The","string","id","associated","with","this","analysis"]
code: def figure_id(self):
      """The string id associated with this analysis"""
      return str(self.analysis)
